Description

The optical fiber connector

The present invention relates to a fiber optic connector.

Optical fiber is a kind of optical transmission tool, mainly made of glass or plastic, which uses the principle of total reflection for data transmission. The optical fiber has the advantages of low loss, high frequency, light weight, small size, etc., so the optical fiber can gradually replace the traditional metal transmission line and be used as a signal transmission medium. In order for the fiber to be connected to various types of electronic devices, connectors and corresponding interfaces are required. The existing optical fiber connector has a complicated structure and is inconvenient to install, and is easy to cause misalignment of the core and the lens of the optical fiber during installation, which is disadvantageous for the development of the optical fiber for data transmission.

In view of this, it is necessary to provide a fiber optic connector that is simple in structure, convenient to install, and low in cost, and is used to promote the development of optical fibers for data transmission.

The present invention provides a fiber optic connector for connecting at least two optical fibers to a corresponding fiber optic interface, the fiber optic connector including a body and a fixed block, the body including a first side, a second side opposite the first side, and a first end surface between the first side surface and the second side surface, wherein the first side surface has at least two lenses protruding therefrom, and the second side surface and the first side surface jointly define a groove, the fixing block is fixedly disposed And at least two fixing holes are formed in the groove opposite to the at least two lenses, the fixing block has a second end surface that is attached to the bottom of the groove, and the bottom of the groove is at the top of the four Four positioning slots are defined in the vicinity of the corners, and the second end surface is provided with four positioning blocks that are inserted into the four positioning slots corresponding to the four positioning slots, and the at least two optical fibers are fixed in the at least two fixing holes, and the optical signals are The optical body is connected to the optical fiber via the body and the at least two lenses.

The optical fiber connector provided by the invention has the advantages of simple structure, convenient installation and low manufacturing cost, and thus can facilitate the development of optical fiber transmission.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of a fiber optic connector in accordance with a preferred embodiment of the present invention.

Figure 2 is an exploded view of the fiber optic connector and fiber of Figure 1.

Figure 3 is an exploded view of the fiber optic connector of Figure 1 and the other opposite direction of the fiber.

Figure 4 is a cross-sectional view of the fiber optic connector of Figure 1 in the direction of IV-IV.

Referring to Figures 1 and 2, the fiber optic connector 1 includes a body 10 and a fixed block 20 secured to the body 10, wherein the body 10 is provided with at least two lenses 15. At least two optical fibers 5 are passed through and fixed to the fixing block 20 for connecting with corresponding interfaces through at least two lenses 15 of the body 10. Each of the optical fibers 5 includes a core 51 and a cladding 52 disposed around the core 51. In the present invention, the number of the lens 15 and the optical fiber 5 corresponds to two.

Referring to FIG. 3 together, the body 10 has a first side surface 11, a second side surface 12 opposite to the first side surface 11, and a first end surface 13 between the first side surface 11 and the second side surface 12, wherein the two lenses 15 are convex Out of the first side 11 . Two tapered posts 14 are also projected on the first side surface 11. After the post 14 is inserted into the interface, the body 10 is fixed in the interface. In the present embodiment, the lens 15 and the body 10 are integrally formed of the same material. The body 10 and lens 15 are capable of transmitting optical signals to the corresponding interface. Place A groove 16 is defined in the second side surface 12 and the first end surface 13. The bottom of the groove 16 is provided with a positioning groove 17 (not shown) near the four corners.

Referring to FIG. 4 together, the fixing block 20 is correspondingly disposed in the recess 16 and has the same shape as the recess 16 described above. The fixing block 20 can be received in the recess 16 just. The fixing block 20 has a second end surface 21 that is in contact with the bottom of the groove 16 , a third end surface 22 that is flat with the first end surface 13 , and a third side surface 23 that is flat with the second side surface 12 . The corresponding four positioning grooves 17 on the second end surface 21 project four positioning blocks 24 of the same shape. Two stepped fixing holes 25 are vertically defined in the third side surface 23, wherein the fixing holes 25 respectively penetrate the fixing block 20 and the axis is perpendicular to the third side surface 23.

When assembling, the glue can be dispensed in the fixing hole 25, and then the optical fiber 5 cut off part of the cladding 52 is inserted into the fixing hole 25, and the glue is solidified so that the optical fiber 5 is fixedly connected with the fixing block 20, and finally the optical fiber 5 is extended out of the fixing hole. Partial removal of 25. After the positioning slot 17 is dispensed, the positioning block 24 is snapped into the positioning slot 17 to fix the fixing block 20 in the recess 16 of the body 10. After assembly, the core 51 of the optical fiber 5 is just aligned with the center of the lens 15 described above. The optical fiber connector 1 provided by the invention has the advantages of simple structure, convenient installation and low manufacturing cost, and thus can facilitate the development of optical fiber transmission.

While the preferred embodiment of the invention has been shown and described, it will be understood Therefore, it is intended that the invention not be limited to the embodiments disclosed herein,
